From 2004 through 2008, the Department of Justice and the Department of Homeland Security (DHS) provided support for
the creation and ongoing maintenance of the Terrorism Knowledge Base® (TKB®), developed and sponsored by the
Memorial Institute for the Prevention of Terrorism (MIPT), based
in Oklahoma City. Through this project, MIPT partnered with Detica
for collection of information on terrorist groups and key leaders of terrorist groups.

TKB® was last updated by MIPT on March 1, 2008, and the project ceased operations on March 31, 2008.

Through an agreement between MIPT, DHS, and START, START is making TKB® group profile data available to the public
through our website. The Terrorist Organization Profiles (TOPs)
presents data collected for and by MIPT through March 2008.

START has not evaluated these data, nor is it responsible for the content of these profiles. START is providing
access to these MIPT data as a service to the homeland security practitioner and research communities.
